Here are some common stomach diseases:

• Gastritis: Gastritis is inflammation of the stomach lining, which can be acute or chronic. It may be caused by bacterial infections (such as Helicobacter pylori), excessive alcohol consumption, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), stress, or autoimmune diseases. Symptoms of gastritis may include abdominal pain, nausea, vomiting, indigestion, and loss of appetite.
• Peptic Ulcers: Peptic ulcers are open sores that develop on the lining of the stomach, duodenum (the first part of the small intestine), or esophagus. They can be caused by infection with H. pylori bacteria, long-term use of NSAIDs, excessive alcohol consumption, smoking, or stress. Symptoms of peptic ulcers may include abdominal pain (often described as burning or gnawing), bloating, nausea, vomiting, and unintentional weight loss.
• Gastroesophageal Reflux Disease (GERD): GERD is a chronic condition characterized by the reflux of stomach acid into the esophagus, leading to symptoms such as heartburn, regurgitation, chest pain, difficulty swallowing, and chronic cough. It can result from a weakened lower esophageal sphincter (LES), obesity, hiatal hernia, or certain dietary and lifestyle factors.
• Gastroenteritis: Gastroenteritis, often referred to as stomach flu, is inflammation of the stomach and intestines typically caused by viral or bacterial infections. It can lead to symptoms such as nausea, vomiting, diarrhea, abdominal cramps, fever, and dehydration. Gastroenteritis is usually self-limiting and resolves within a few days with supportive care, including hydration and rest.
• Gastric Cancer: Gastric cancer, also known as stomach cancer, is a malignant tumor that develops in the lining of the stomach. It is often diagnosed at an advanced stage due to nonspecific symptoms such as abdominal pain, unintentional weight loss, nausea, vomiting, and difficulty swallowing. Risk factors for gastric cancer include infection with H. pylori bacteria, smoking, a diet high in salted, smoked, or pickled foods, and certain genetic factors.
• Functional Dyspepsia: Functional dyspepsia is a chronic disorder characterized by persistent or recurrent upper abdominal pain or discomfort without any identifiable cause. Symptoms may include bloating, belching, early satiety (feeling full quickly), and nausea. The exact cause of functional dyspepsia is not well understood but may involve abnormalities in gastrointestinal motility, visceral hypersensitivity, or alterations in gastric acid secretion.
